C16 vs Q16

This is straight off VP racing fuels website:

"Q16 is simply the best drag race fuel ever made. And coming from VP Racing Fuels, that’s a big statement. Q16 represents true world class technology. With more power, octane and consistency, Q16 will work well not only in drag racing, but circle track and off road, spanning the application range better than any fuel ever made—from naturally aspirated to nitrous to blowers. It’s recommended for engines with compression ratios up to 17:1.

Power – Q16 has 10% oxygen content by weight, requiring a 4-6% increase in fuel flow, which contributes to making 3-5% more power than competitors’ fuels. With its rapid vaporization rate, Q16 has superior burning speed and makes more pressure in the cylinders, both of which also make more power. Q16 still has relatively low vapor pressure, unusual in a fuel with an oxygen content and vaporization rate this high.

Octane – Q16 has a motor octane of 116, virtually the same as VP’s C16, but its resistance to detonation is even better—6 to 8 numbers higher than its standard ASTM rating—due to the increased fuel flow. This is particularly relevant to circle track, dirt track and off road racing where radiators and air ducts can get clogged by dirt and debris. While this occurs during the course of a race, octane requirements will change, but Q16’s effective octane rating will preclude detonation throughout such conditions. Notably, Q16 also will contribute to lower engine operating temperatures due to more efficient combustion which yields lower exhaust gas temperatures.

Consistency – Due to its oxygenated compounds and better vaporization, Q16 offers a wider air-fuel ratio and improves fuel distribution cylinder to cylinder. This means a Q16-powered vehicle will be much more consistent run to run and won’t vary as dramatically with altitude or density changes."
 
Q16 works better in intercooled set-ups for a noticable power increase but...... C16 works better in the non-intercooled turbo set-ups because it handles the higher air intake temps better!
 
looks like the q16 (according to vp anyway) is a better all around fuel for racing.
